Digital watermarks
View Patent ↗The present invention relates generally to digital watermarking, steganographic data hiding, and data compression. One claim recites a method including: obtaining media comprising imagery or audio; obtaining plural-bit data; embedding the plural-bit data in the media with digital watermarking, the digital watermarking altering data representing the media; and adjusting compression of the media in accordance with at least one characteristic associated with the digital watermarking. Other claims and combinations are provided as well.
1. A method comprising:
receiving a media signal representing imagery or audio;
receiving auxiliary data to be steganographically hidden in the media signal;
receiving an indication of whether compression of the media signal can be adjusted;
utilizing a programmed multi-purpose electronic processor, hiding the auxiliary data in the media signal through alterations to data representing the media signal; and
utilizing a programmed multi-purpose electronic processor, compressing the media signal in accordance with at least the indication.
2. The method of claim 1 wherein the indication further comprises information to adjust the compression of the media signal.
3. The method of claim 2 wherein the information comprises a relative degree of compression.
4. The method of claim 1 wherein the data representing the media signal comprises at least transform domain coefficients.
5. The method of claim 1 wherein the data representing the media signal comprises at least audio values or video values.
6. The method of claim 1 wherein the act of hiding utilizes at least a transform domain.
7. A method comprising:
obtaining media comprising imagery or audio;
obtaining plural-bit data;
utilizing a configured multi-purpose electronic processor, embedding the plural-bit data in the media with digital watermarking, the digital watermarking altering data representing the media; and
adjusting compression of the media in accordance with at least one characteristic associated with the digital watermarking.
8. The method of claim 7 further comprising receiving an indication including information regarding how to adjust the compression of the media.
9. The method of claim 8 wherein the information comprises a relative degree of compression.
10. The method of claim 7 wherein the data representing the media comprises at least transform domain coefficients.
11. The method of claim 7 wherein the data representing the media comprises at least audio values or video values.
12. A computer readable medium comprising instructions to perform the method of claim 1 .
13. A computer readable medium comprising instructions to perform the method of claim 7 .
14. A programmed computing device storing instructions in memory, said instructions are executable by said programmed computing device to perform the acts of claim 7 .
15. A computer readable media comprising instructions stored thereon to cause a multi-purpose electronic processor to perform the acts of claim 7 .
16. A programmed computing device storing instructions in memory, said instructions are executable by said programmed computing device to perform the acts of claim 1 .
17. A computer readable media comprising instructions stored thereon to cause a multi-purpose electronic processor to perform the acts of claim 1 .
